NYC Teacher Distribution by Years of Service

Joel Klein recently announced the number of teachers in the Absent Teacher Reserve (ATR) pool, including a breakdown of teachers by years of service. One common question is how these numbers compare to the overall distribution of active DOE teachers. Using information from the DOE, I found that younger teachers are underrepresented in the ATR pool at 13 percent versus 29 percent of active teachers. Teachers with 15 to 25 years of service are overrepresented in the ATR pool, at 31 percent versus 19 percent of the active teachers. The current breakdown of active teachers in the DOE as well as the breakdown of teachers in the ATR pool are shown in the pie charts below.

  • I noticed that…

    If that’s not discrimination of ATRs who are senior teachers based on the above graph, then take my blackboard away and never give me a piece of chalk!

    Are the actual numbers available?

    (those red regions are awfully large. Would be nice to break them down further)

    Thanks.
    My suspicions are confirmed as to the “what.”
    Perhaps now we can move on to the “why.”

    As to the two histograms: I’d be curious as to the two medians. Median age looks like around 40. Median experience looks like around 10. Does that mean the median teacher started at age… 30?

    The median experience is likely to be skewed low within that larger region. Trying to read the bar chart, I get about:
    less than one year 5k
    1 – 4 years 17k
    5 – 9 years 21k
    10 – 14 years 13k
    15 – 19 years 8k
    20 – 24 years 7k
    25 and up 6k?

    less than one year 6%
    1 – 4 years 22%
    5 – 9 years 27%
    10 – 14 years 17%
    15 – 19 years 10%
    20 – 24 years 9%
    25 and up 8%

    Median could be 8?
